The valley of Ceylon, which means "Golden Land" or "Land of the Dawn," was designed by the architect Mantru and constructed through the toil of many Aldar to be the home of the first humans. It was ordered built by Ayar as a dwelling place for the Offspring, the seven children of Callisto and Sinope. The Offspring eventually left to pursue their own goals. Those who stayed behind suffered further losses from a plague, and the final bit of human survivors left on a journey across the Mhojave Desert to purge the plague from them, eventually reaching the cave system known as Moghedu where they evolved over time into present-day mhun. In this way Ceylon was abandoned, and its location lost to history.
